Cuyahoga County sits inside EPA Radon Zone 1 — the highest-risk category in the United States. Roughly one in three homes tested in this region comes back above the EPA action level of 4.0 pCi/L, and North Royalton's clay-heavy soils and finished basements make it one of the worst pockets in the county. If your inspection report came back high, you are not overreacting. You have a real problem with a permanent fix.

Radon Eliminator is a licensed Ohio radon mitigation contractor (Ohio Mitigation License RC202) serving North Royalton, Broadview Heights, Strongsville, Brecksville, and the rest of southern Cuyahoga County. We install code-compliant active soil depressurization (ASD) systems, run EPA-aligned post-mitigation tests, and document every number for your closing file, your school board, or your apartment portfolio.

We do not sell fans. We sell a number under 4.0 pCi/L — measured, signed, and warranted. That is the difference between Radon Mitigation North Royalton OH homeowners actually want and the generic fan-on-a-wall installs they often get.

• Ohio License RC202 — stated on every quote, every permit, and every report.
• Closing-Date Radon Service — testing and mitigation scheduled around your purchase agreement, not our convenience.
• Multi-vertical experience — single-family, multi-unit apartments, K–12 schools, and commercial buildings.
• Guaranteed result — post-mitigation test under 4.0 pCi/L or we keep working at no cost.
• Transparent flat pricing — no surprise diagnostic fees, no day-of upcharges.

Every North Royalton home is different — a 1960s ranch off Royalton Road has a different sub-slab profile than a new build in the Hunting Meadows subdivision or a townhome near Memorial Park. Our certified team designs each mitigation system around the specific foundation, soil, and HVAC conditions of your property. Below are the core services we deliver across the city.

For the typical North Royalton single-family home, we install an active sub-slab depressurization (ASD) system using a sealed suction point, schedule-40 PVC routed through a non-living-space chase, and a properly sized radon fan (RadonAway RP145, GP501, or HS series, depending on slab permeability). Exterior runs are mounted cleanly with UV-rated pipe and discharge a minimum of 10 feet above grade and away from windows — per EPA and Ohio Department of Health standards. Most homes are completed in a single day.

If your inspection came back hot and you have 10–14 days to close, this is what we built our business around. We can deploy a continuous radon monitor within 48 hours, complete mitigation install typically within 3–5 business days of contract, and provide signed post-mitigation results in time for the title company. Agents at Howard Hanna, RE/MAX, and Russell Realty across North Royalton already use us on deadline files — ask for the Closing-Date Radon Service when you call.

Ohio Revised Code holds commercial property owners, multi-family landlords, and school districts legally accountable for safe radon levels. We design multi-point ASD systems for apartment complexes along Ridge Road and State Road, sub-slab suction grids for warehouses near the I-71 corridor, and HVAC-integrated solutions for schools in the North Royalton City School District. Every commercial project includes engineered drawings, building-department permits, and a documented post-mitigation report suitable for compliance files.

Installation without verification is malpractice. We run a 48-hour EPA-aligned post-mitigation test on every system. If your existing radon system was installed by someone else and you suspect it is no longer pulling — manometer flat, fan loud, or recent retest above 4.0 pCi/L — we offer full diagnostic inspections, fan replacements, and upgrades to bring legacy systems back into compliance.

The process below is the same whether you are a homeowner on Bennett Road or the facilities director for a 200-unit apartment community. Predictable, documented, defensible.

1. On-Site Diagnostic Assessment. We inspect the foundation, identify slab type (poured, block, crawlspace, or mixed), locate utilities, and choose the optimal suction point. For North Royalton's common split-level and bi-level homes, suction location is what separates a system that hits 1.2 pCi/L from one that limps along at 3.8.

2. Engineered System Design & Flat-Rate Quote. You receive a written scope, the fan model we will install, the exact pipe route, the warranty terms, and the total price — before we lift a tool. No diagnostic fees added later.

3. Same-Day Code-Compliant Installation. Our licensed crew installs the ASD system per Ohio Department of Health standards: sealed suction pit, PVC routing, system label, U-tube manometer, exterior fan, and proper discharge. We pull permits when required and clean the workspace before we leave.

4. EPA-Aligned Post-Mitigation Verification. A 48-hour continuous radon test confirms the result. You receive a signed report showing pre- and post-mitigation pCi/L levels — the document realtors, lenders, and inspectors actually need.

North Royalton sits on glacial till and shale-derived soils that release uranium decay products — the geologic source of radon gas. Combined with tightly sealed modern construction and the prevalence of finished basements used as bedrooms, family rooms, and home offices, the city has measured radon averages well above the national mean. The Ohio Department of Health's county data ranks Cuyahoga County among the state's elevated-risk zones, and North Royalton ZIP code 44133 returns elevated short-term test results at higher-than-average rates.

We work daily in neighborhoods including Royalwood Estates, Hunting Meadows, Edgerton Estates, the homes surrounding North Royalton Memorial Park, and the older builds near Ridge Road and State Road. We know the local building stock — including the common 1970s tri-levels with a finished lower level under grade, where children's bedrooms are routinely placed in the highest-radon zone of the house. That is exactly the configuration that keeps parents up at night, and exactly what our systems are engineered to fix.

We also serve the surrounding municipalities — Broadview Heights, Strongsville, Brecksville, Parma, Hinckley, and Independence — with the same licensed crew, same flat pricing, and same guaranteed result.

Most North Royalton single-family homes fall into one of three flat-rate tiers:

• Standard interior or exterior ASD install: $1,295 – $1,695. Covers the vast majority of poured-slab basements and slab-on-grade homes.
• Complex installs (multiple suction points, block foundation, crawlspace encapsulation): $1,795 – $2,795.
• Commercial, multi-family, and school projects: Quoted after engineered site assessment.

Standalone radon testing for real-estate transactions runs $145–$195 for a 48-hour continuous monitor test with a signed report. We do not charge a separate diagnostic or trip fee when you proceed with mitigation.
